W32Time

Time Provider NtpClient: This machine is configured to use the domain hierarchy to determine its time source, but it is the PDC emulator for the domain at the root of the forest, so there is no machine above it in the domain hierarchy to use as a time source. It is recommended that you either configure a reliable time service in the root domain, or manually configure the PDC to synchronize with an external time source. Otherwise, this machine will function as the authoritative time source in the domain hierarchy. If an external time source is not configured or used for this computer, you may choose to disable the NtpClient.

W32Time

The time service has not been able to synchronize the system time for 49152 seconds because none of the time providers has been able to provide a usable time stamp. The system clock is unsynchronized.

The time service has detected that the system time needs to be changed by -2591998 seconds. The time service will not change the system time by more than -54000 seconds. Verify that your time and time zone are correct, and that the time source xxxx.xxxx.xxx (ntp.d|xx.xx.xx.xx:123->xx.xx.xx.xx:123) is working properly.
